I wanted to know about your opinion and maybe how did you solve this level.
Have you used libraries like tesseract-ocr, gocr, etc, or did you made an ocr logic yourself? Do you think it worth to make a simple ocr library from scratch, or this is reinvent of the wheel?

There is nothing wrong with reinventing the wheel. You can learn a lot from it and perhaps even discover a better wheel.

For the first captcha a tesseract can works if you use correctly about the next capthcas I think that the easy way is create a captcha reader by yourself. To more opinions about codes pm me if you need help to not post code here and spoil the challenge.

I used tesseract-ocr for this challenge. For captcha 2,3,4 I made something custom.

A small hint if you use tesseract-ocr: It did not work ‘out of the box’ for me.

Thanks. This is a expression I think ‘box" like a common sentence and don’t understand but know the meaning is clear.

Once you have reinvented the wheel twice or thrice, you may also become lazy and find appeal in other users' wheels.

I guess I was already born lazy then @tehron

A beginner practices until he gets it right, a professional practices until he can’t get it wrong!

Me not. I just think the wheel is always greener on the other side.

You should use it more often; a rolling wheel gathers no moss.

Nice, I think I`ll make my own OCR solution.
I tried to do that some weeks ago, and I learned a lot, but I need to learn more!
